Question : JavaScript: Require at least one letter or number

I want to require at least one letter or number.

1: 2:

var str='!@#'; if(str does not contain at least one letter or number) alert('Must contain at least one letter or number');

Answer : JavaScript: Require at least one letter or number

Which ID drives the report as there are 4 tables? Also I note that in your ER diagram that you have a Practice_ID field in the practice table but the primary key is the Practice_Name field.
Is this intentional?

Did you enforce relationships between each table?
